Hey Jack. Thanks for your interest.
I'm not sure if this will fix but could you try again with the latest Pd-0.48-1 and not the test version? You can download it from here http://msp.ucsd.edu/software.html
I personally tested ofelia on Ubuntu LTS 16.04, Ubuntu Studio 17.10 and Linux Mint 18.3. For me, it worked fine on these distros even without installing dependencies.sh
If the problem still occurs please let me know. You can also send me a personal email. cuinjune@gmail.com
Thanks.
Zack
